Both basic activity of daily living (BADL) and instrumental activity of daily living (IADL) were measured.Results: A total of 4621 oldest-old (≥80 years old) were included. 32.1% (1482) of the oldest-old had BADL disability and 79.0% (3129) had IADL disability. The BADL disability and IADL disability rates were higher for participants with COPD than those without, and this difference was more robust among male (31.8% vs 25.6%, p=0.018). The IADL disability rate showed similar trends. Multivariate logistic regression analysis showed that the odds ratios of COPD on BADL disability and IADL disability were 1.261 (95% CI: 1.044–1.525) and 2.014 (95% CI: 1.561–2.598), respectively. The odds ratios of COPD on moderate to severe BADL disability and IADL disability were 1.007 (95% CI: 0.790–1.284) and 1.713 (95% CI: 1.397–2.100), respectively.Conclusion: There were independent associations between COPD and disability among oldest-old in People’s Republic of China, and the associations were greater among male population. Besides, COPD had a profound influence on the mild disability of BADL, while had a greater impact on the moderate and severe disability of IADL.Keywords: chronic obstructive pulmonary disease, activity of daily living, oldest-old
